Patented July 3, 1906.

Application filed March 12, 1906'. Serial No. 305,490-

To all whom it may concern.-

. Be itknown that I, ALBERT LANG, doctor =of philosophy, chemist,,professor at the Tech- .mc'al'Hi h School, and a resident of 7 Weberstrasse, arlsruhe, in the Grand Duchy of Baden, German Empire, have invented new and useful Improvements in Heating De- -;vicesfor Tins, of which the following is a =i'1y'glowin without flame is used, The car' tridge is p aced in a cavity in the bottom of the tin and is covered by'alid, A fuse or slow match is used to set the contents of the cartridge alight without removing the bottom lid.

In the accom anying drawings, Figure 1 is 'a section, and ig. 2 a plan view, partially in section.

1 is the tin, 2 the rounded bottom of the tin, 'and'3 the lid covering the cavity formed in the rounded bottom. Fixed to the lid 3 is a ring 4, having a collar 7 to hold the cartridge 5 A late 6, of refractory mate- 1 radiation of heat.

rial, is placed un er the cartrid e to prevent Holes 8 in t e rin and 9 in the lid serve for the introduction 0 a slow match or fuse from the outside into the cartridge to allow of its being kindled from vent destruction of the bottom 2 of the tin,

This plate 13, of refractory material, is held in position by bent fingers 14 of the ring 4.

The parts 1, 2, and 3 and the cover 11 are united in the usual way, .and the tin is opened inthgusual way by tearing off the band 12.

In 15 sin the tin the band 12 is torn off and the cartrldge kindled by the fuse or slow 4,5 match .15. After three or four minutes time the contents of the tin are heated to 70 to 80 centigrade.

The tin may be used for heating tea or coffee after em tying and cleaning it, as the development 0 heat continues for some time by the cartridge.

What I claim is 1. The combination with a reserved-food tin having a rounded bottom ormin a cavity and a lid covering the cavity, 0 a cartridge of heating material located in said cavity and a ring fixed to said lid arranged to hold the cartridge in place, said ring and lid having holes therethrough for the insertion of a slow match or fuse into the said cartridge without removing the lid.

2. The combination with a reserved-food tin having a rounded bottom ormin a cavity and a lid covering the cavity, 0 a cartridge of heatin material located in said cavity, a ring fixe to said lid arranged to hold the cartridge in place, fingers on the said ringand a plate of refractory material held in position etween the cartridge and the bottom of the tin by said ring-fingers.

3. The combination with a reserved-food tin having a rounded bottom orming a cavity and a lid covering the cavity, of a 'cartridge of heating material located in said cavity, a ring fixed on said lid arranged to hold the cartridge in position, fin ers on said ring, a plate of refractory materia held in position between the cartridge andthe bottom of the tin by said fingers and a second plate of refractorymaterial interposed between the bottom of the cartridge and the bottom lid.

In 'testimon that I claim the foregoing as my invention have signed myname, in resence of two witnesses, this 22d day of ebruary, 1906.
